Mucenex: It is just fine to take Mucinex (guaifenesin) daily. Mucinex (guaifenesin) is no more then solid Robitussin. The exception to this would be Mucinex (guaifenesin) D which has a decongestant in it. This can still be taken daily but should not be taken more then for a week without a break. This is because the decongestant also artificially stimulates the heart and it is not good for the heart to constantly be having a stimulation.
